Clay is hydrated aluminium silicate and iron iii oxide having chemical formula Al 2 O 3 SiO 2 Fe 2 O 32H 2 O. The chemical formula of China clay is Al2Si2O5OH4. The picture below shows the structure of the smectite-illite clays with the sandwich-type repeat unit.

METHODS Clay Sample Separation Clay minerals were separated from the rock matrix by carefully crushing the portion of the rock of interest followed by hand separa-. There are many commercial Kaolinite mines where this mineral is mined in large volumes for its various industrial uses. Thus clay consists of aluminium oxide Al 2 O 3 silicon dioxide SiO 2 and iron iii oxide Fe 2 O 3 along with water molecules.

Expandable 21 clay minerals exhibit a. Montmorillonites are three. Iron oxide - 8.

Kaolinite also has a very similar chemical formula to Serpentine and is sometimes considered a member of the Serpentine group. MINERALOGY AND CHEMICAL COMPOSITION OF CLAY MINERALS 279 Fe2O3 differences in total Fe as Fe 2O3 incorporated into clay matri-ces may indicate changes in chemical environment of formation. Some clay minerals may be expressed using ideal chemical formulas as the following.

Silica is present in brick clay as the chemical composition of alumina and forming silicate of aluminaSometimes silica is present in pure form termed as flint. The Y represents either aluminum silicon boron or iron but mostly aluminum and silicon. The SiO 2 ratio in a formula is the key factor determining clay.

Kaolinite is the most common clay mineral and entire clay deposits can be composed of this mineral. How the exact chemistry of a healing clay affects the end efficacy is not known. However the structures of these minerals are poorly defined and likely to be representative of a mixture of weathered micas.

To occur in varying amounts in these fine-grained or clay-sized micas 1. Al2O34SiO2H2O Reade Advanced Materials Montmorillonite Chemical Equation. The Chemical formula of ball clay is Al 2 O 3.

Kaolin Al2H4O9Si2 CID 56841936 - structure chemical names physical and chemical properties classification patents literature biological activities safetyhazardstoxicity information supplier lists and more. While advanced ceramics consist of carbides SiC pure oxides Al2O3 nitrides Si3N4 non-silicate glasses and many others.

The clay substance may he shoiWll by the follQlwing equation as the result of the action of walter and carbon dioxide upon feld. KAlSi8AlOOHusuallywith 1y y4-yy204 15butalwayswithy2. Ball clay should never tested for colour in the concentrated state since its density and adsorbed salts give colour intensities which are misleading.

The X represents either aluminum iron lithium magnesium manganese nickel zinc or rarely chromium. One formula given for a granular Wyoming bentonite. Illite and glauconite dioctahedral iron illites are commonly associated with the clay-sized micas.

Clay Mineralogy 2nd edition McGraw-Hill Book Company New York 1968 41. There are many different clay minerals. Na02Ca01Al2Si4O10OH2H2O10 Sodium bentonite is the name for the ore whose major constituent is the clay mineral sodium montmorillonite.
